Abstract

Objectives: To examine the difference in smoking related self efficacy (SE) on three stages of the smoking continuum among a sample of form one students.

Methods: A total of 2328 form one students were assessed using self administered questionnaire. Test retest reliability was used to measure consistency of the instrument over time. Self efficacy (SE) subscale had a high alpha reliability, 0.93. SE to refuse cigarette smoking was evaluated using 4-item scale measuring with a total score ranging from 4 to 16 with higher score reflecting higher SE to avoid smoking. Ever-smokers were categorized either as experimenters, current smokers or ex smokers. This abstract reports part of the finding from a longitudinal study related to adolescents smoking and factors influencing the transition of smoking stages.

Results: 16.2% of the respondents were ever smokers. 6.3%, 6.6% and 3.3% had experimented, had regularly smoked and had quit smoking respectively. Mean SE score was 13.99 +_ 2.54. Levene test showed equal variances. The One way ANOVA test was significant (p<0.001). Subsequent post hoc analyses (Scheffe procedure) suggest that the mean SE score was significantly different between "experimenters and smokers" and "smokers and ex-smokers".

Conclusion: Current smokers had lower smoking refusal self efficacy compared to experimenters and ex-smokers. Efforts to increase smoking related self efficacy of adolescents should be encouraged.
